APPARATUS FOR CENTRIFUGALLY TREATING MOLTEN MATERIAL.

SPECIFICATION forming part of Letters Patent No. 433,144, dated July 29,1890. Application filed March 3, 1890. Serial No. 342,435. (No model.)

To all whmn it may concern..-

Be it known that I, ORRIN l3. PECK, a citi-.

zen of the United States, residing at Chicago, Illinois, have invented anew and useful Improvement in Apparatus for Centrifugally 'lreatingMolten Material, of which the following is a specification.

The object of my invention is to provide a simple and economical meansfor treating and removing the molten material, and also for removing thegas and steam that may be formed; and the invention consists in thefeatures and combinationshereinafter described and claimed.

In the drawings, Figure 1 is a vertical elevation, partly in section, ofthe centrifugal machine, together with the apparatus for removing thematerial and the gas and steam; Fig. 2, a plan view of the entireapparatus; Fig. 8, a horizontal section on line 3 30f Fig. 1, looking inthe direction of the arrows; and Figs. 4, 5, and 6, vertical sectionsillustrating modified forms of discharging-sportts. The last fourfigures are on an enlarged scale. Fig. 7 is a detail plan view of ascreen.

V is the receiving-vessel; A, the curb surrounding the same; 15, theshaft for supporting and revolving the vessel; C C, journalbearings forsupporting and maintaining the vertical position of the shaft; D, thedischarge pipe or passage; E, a centrifugal pump; F, a discharge-pipeleading off from the pump; G G, rollers or crushers mounted in thedischarge-pipe and driven by means of a beltwheel G and cog-wheels g g;g, a weighted lever intended to hold the rollers G G in proper relativeposition to each other; ll, an exhaust or suction fan connected with thedischarge-passage D by means of pipe 71, and provided with adischarge-pipe ll 5 I, a suitable engine for supplying power to drivethe pump and fan; J, an engine for supplying power to drive thecentrifugal machine; J the driving-wheel thereof, and K the drivingbelt.

The receivingvessel, curb, shaftll, with its bearings, engine fordriving the centrifugal machine, and all parts not hereinafter moreparticularly set forth have been shown and described in prior patentsand applications, and their construction being obvious from aninspection of the drawings, they require no further description.

From a point, preferably near the bottom of the curb A, I lead oif asuitable discharge pipe or passage D and connect it with a centrifugalor other force-pump E, by means of which the material which flows out ofthe curb is forced through the pipe F to any place desired. Throughimperfect or insufiieient cooling, comparatively large lumps of materialare liable to be formed in the machine, and, passing down through thedischargepassage, will clog or interfere with the action of the pump.-To prevent this interference with the pump, I prefer to provide rollersG G. These rollers are supported, as shown, in the discharge-passage,and are provided with cog-wheels g, which mesh together. The shaft ofone of these rollers is provided with a beltwheel G, driven by anysuitable source of power, as the engine I. These rollers are constantlyrevolving, and should be so placed in the discharge-pipe that thematerial coming through the machine is forced to pass between them, andany lumps too large to pass between the rollers will be crushed orreduced in size by their revolution. One of these rollers or crushers Gis supported in a movable hearing L,the objeetofthis being to allow aslight play to the rollers.

In Fig. 4 I have illustrated a modification of this crushing device,wherein the surfaces of the crushing-rollers are provided withcorrugations.

In Fig. (3 I have shown a modification wherein I have substituted forthe crushingrollers G a movable crushing-j aw M, operated by atoggle-joint N, or other suitable mechanism. In the modification shownin Fig. 5, D is the suction-pipe of the pump E, and D is the end of thedischarge-spout, preferably somewhat contracted toward its lower end. Atsome point between the pump E and the curb of the centrifugal machine Iprovide a screen 0, made of such size as to permit only of the passageof such material as is proper to pass through the pump. The largerpieces which are rejected by the screen pass down and out of a suitableopening in the pipe or passage D.

In the use of thecentrit'ugal machine for the treatment of moltenmaterial a large amount of gas and steam is formed, and to provide themeans for carrying off such gas and steam I employ a suitablesuction-fan H, or other means connected, as shown in the drawings, withthe discharge pipe or passage by means of the pipe h. The fan may,however, be connected, directly to the curb of the machine or any othersuitable part of the apparatus.

In my applications Serial Nos. 342,425, 342,427, and 342,437, filed atthe same time as my application herein, I have set forth the process andsome of the features of construc-' tion disclosed, but not claimed inthis case.

I claim- 1. The combination, with a centrifugal machine for thetreatment of molten material, of an exhaust-fan for drawing off steam orsmoke, and a pump for pumping away material andwater, substantially asdescribed.

2. The combination, with a centrifugal machine for the treatment ofmolten material, of a force-pump for pumping away the water andmaterial, a spout connecting the machine and pump, and an exhaust-fancommunicatingwith the pump, substantially as described.

3.. The combination, with a centrifugal machine for the treatment ofmolten material, of a force-pump for pumping away the water andmaterial, a spout connecting the machine and pump, and means forcrushing coarser material on its passage from the machine to the pump,substantially as described.
